1. How to build a nice topographic profile

2. Mark initial point 2 cm away from the margin

3. Fold the margin
Fix your letter A with the one in the map and
mark final point (B) in the graph paper

4. Mark in the margin every contour line that you come accross

5. Mark the elevations that you know looking at the countour lines
